Garmin Fenix 8
The Garmin Fenix 8 is the undisputed king of rugged multisport expedition watches, merging AMOLED and Solar options across three sizes while adding leakproof inductive metal buttons rated for 40-meter scuba diving, a built-in multi-LED flashlight, and speaker/mic voice commands. With 16-to-29 days of AMOLED battery life (up to 48 days on Solar) and 32GB of offline TopoActive maps, nothing else matches its off-grid self-sufficiency.
Apple Watch Ultra 3
Encased in 49mm aerospace titanium with a flat sapphire crystal, 3,000-nit wide-angle LTPO3 OLED display, and EN13319 40-meter dive certification, the Apple Watch Ultra 3 is the most capable smartwatch Apple has ever built. Dual-frequency L1+L5 GPS tracks urban marathons with surgical accuracy and 36-to-72-hour battery life comfortably clears weekend adventures, making it the definitive choice for iPhone athletes who want one watch for the trail and the boardroom.
